LONG-STAPLE-FIBER-PULLING MACHINE.

Specification of Letters Patent.

Patented Feb. 18, 1913.

Application filed November 2, 1911. Serial No. 658,267.

b all 1.0 71 0m, 2' t m 611 concern Be it known that 1, WILLIAM RraxSIB- en'r'r, a citizen of the United States, residing at Seventh andPoplar streets, Oakland, in the county of Alameda and State of California, have invented a new and useful Long Staple Fiber PullingMachine, of which the following is a specification in such full andclear terms as will enable those skilled in the art to construct and usethe same.

This invention relates to a machine for the production of what is knownas wiping waste from cloth which is practically worthless.

It will be understood by those skilled in the art that a great deal ofwiping waste is used about machines for wiping oil oil and dirt. Thiswaste is usually the scraps of all kinds from thread or cloth makingestablishments and is worth from 4: c. to 10 e. per pound.

It will be further understood by those skilled in the art that all sortsof clothing manufacturing establishments waste great quantities ofmaterial in the shape of small bits, which are too small to be used foranything in connection with the clothing made. These scraps of cloth areusually thrown away or sold for a nominal sum.

The principal advantage sought with this machine is to produce longthread waste from such scraps of material, or at least as long threadsas possible, considering the smallness of the scraps used.

A further object of this invention is to produce a machine which willdraw the threads from the cloth with as small breakage as possible, thisbeing accomplished by means of a resilient cutting bed, against whichthe cloth is held while being torn apart.

In the drawings in which the same numeral of reference is applied to thesame portion throughout the several views, Fig ure 1 is a side elevationof the complete machine. Fig. 9. is a sectional view of the completemachine. Fig. 3 is a plan view of the complete machine, and Fig. 4 is asectional view, on a large scale, of the serrate holding disks, movablecutting bed and shredding drum. Fig. 5-is a plan view partly in sectionof the feeding mills, and portion of the bar supporting the presserplates thereof and two of said presser plates, and Fig. 6 is a view inelevation of one of the toothed presser plates, the shank which supportsit and the spring which holds it in contact with the feeding mills.

The machine has a base frame 1, uprights 2, 3 andl, on which uprightsare supported rails Mounted upon the rails 5 are journal boxes 6 and 7,there being two of each; the former for supporting one end of the feedapron and the latter for supporting the shaft of the shredding drum.Between the boxes 6 and 7, on the rails 5, are supports 8. The supports8 have bearings therein for shafts 9, 10 and 11.. At the top, thesupports 8 support a cross bar 12, which cross bar is suitably boltedthereto and carries a plurality of slid-able heads 13, shanks 14 thereonpassing through the bar 12. Each shank 14 has a spring 15 surroundingthe same and is prevented from moving the bar on shaft S) more than afixed distance by means of a nut 16. Each head 13 has a spring 17secured thereto, said spring being slotted to form a comb at 18. Theshaft 9 has mounted thereon a plurality of saws or mills 1.) and aplurality of washers 20, the washers spacing the saws a short distanceapart.

A feed belt 21 passes over the drum 22 on the shaft 23 journaled in theboxes 6 and over the shaft 11. The saws or mills 19 are so placed as tohold the material fed thereto from moving forward unless said materialis thoroughly torn apart. Rolls 24.- on shaft 10 assist in feeding thematerial into the machine. The journal boxes 7 carry a shaft 25, whichshaft supports a drum 26, of any suitable material and the drum isprovided with a number of teeth 27, said teeth being closely arranged onsaid drum in order to tear the material fed thereto completely acrossthe machine.

The actual machine has about 220 of the saws or mills 19 in a width of36" but there is only a small number shown in this drawing for purposesofillustration.

Supported below the saws or mills 19 is a shaft 28, which shaft formsthe support for the members 29 which form the resilient cutting bed. Themembers 29 are thin steel plates, having one end curved in toward thecircumference of the washers 20 as shown at 30, while at 31 each member29 is provided with a projecting hump which tends to force the materialfed into the machine outwardly into the path of the teeth on the drum26.

The members 29 are all placed upon the shaft 28, washers or separators32 holding said members 29 the same distance apart as the saws or mills19 so that there is a mem ber 29 opposite each washer or separator 20.At the lower end of the member 29 there is a plate 33, said plate beingsuitably secured to a cross bar 34. This plate 33 is slotted so that thelower end of each member 29 works in line with the separators on theshaft 9. Each member 29 is connected by means of a spring 35 to a crossbar 36, ex tending from the posts 3 entirely across the machine.

At the discharge end of the machine there is a bracket 37 at each sideof the machine, each bracket supporting a journal box 38. Each bottomrail of the machine supports journal boxes 39, 40 and 41. The boxes 38have a shaft 42 therein and the boxes 39 have a shaft 43, said shaftsupporting suitable cylinders 44 and 45 respectively, over which passesthe discharge apron 46. The

boxes 40 support a shaft 47 while the boxes 41 support a shaft 48. Eachof the shafts 42, 43, 47, 38 and 9 are provided with suitable pulleys,while the shaft 25 is provided with two pulleys, the larger of which hasa belt 50 passing thereover from a motor 51 on the base of the machine.

Any suitable driving mechanism for the several revoluble parts of themachine may be used. In the present instance the motor 51 has a belt 50passing over its pulley and connected with the driving pulley of thelarge drum 26. Also connected with the large drum is a belt 53, whichbelt passes around the pulley on the shaft 48. This shaft has anotherpulley thereon over which passes a belt 54, said belt also passing overa loose pulley on the shaft 43, from which loose pulley a cross belt 52passes around a pulley on the shaft 47 This shaft 47 is provided withanother pulley and a sprocket wheel 58, which. drives the mills or sawsby means of a sprocket chain 56, said sprocket chain preventing the sawsfrom being rotated too rapidly.

Extending from one of the pulleys on the shaft 47 is a belt 54, whichdrives the belt 46 in such a direction as to cause the dis charge fromthe machine on a shaft 42. This shaft 42 has another pulley thereon overwhich passes a belt 55, said belt 55 passing over a loose pulley on theshaft 9 and driving the belt 21 from a belt 55.

The particular driving mechanism, however, forms no part of theinvention and is simply inserted for purposes of illustration and anyother arrangement of belts may be used, as deemed necessary.

The mill teeth and the teeth on the shredding drum move in the samedirection, but

number of teeth on the shredding drum have passed any given positionthereof, thus completely pulling it apart.

The operation of the machine is as follows: The motor is started and theshredding drum moves in the direction indicated by the arrow, whereuponthe feed belt 21 moves forward and delivers the small bits of cloththrown thereupon to the feed rolls 10 and mills 19. It will be observedthat the mills 19 have their teeth facing in such a direction as toprevent the clot-h from be ing pulled therefrom by the shreddingcylinder. As the cloth is carried under the feed rolls 24 and under thestiff springs 17 and combs 18, it is brought into contact with thepoints of the shredding cylinder. The projections 31 on the members 29hold the cloth against the teeth of the shredding cylinder. Since themembers 29 are only held in place by means of the springs 35, pressureagainst the bits of small cloth causes said members to move away fromthe shredding cylinder, thus pulling the cloth apart thread by thread,and not tearing it as would happen if the shredding cylinder operatedagainst a fixed bed.

It is to be understood that the term saws and the term mills, as used inthis specification, refers to disks, which are serrated in the manner ofthe teeth on a hand rip saw, although said serrated disks are not forthe purpose of cutting at all but are merely for holding the goods whilethe shredding drum pulls the threads therefrom.

It is to be further observed that while this machine has been especiallymade for the production of wiping waste that it is possible to producelong staple cotton and wool from cloth cuttings with a machine having aresilient cutting bed properly adjusted and the speed of the shreddingdrum properly adjusted to the product to be made.

It is thus possible to produce from a great assortment of cloth, aproduct which can be made into yarns for weaving the grades of fabricsuited thereto.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States, is as follows:

1. In a machine for the production of waste, a plurality of revolubletoothed feeding mills, a feed roller thereover, springs bearing uponsaid mills to hold materials fed thereto in close contact therewith, arevoluble toothed cylinder and a flexible bed, over which the materialsto be torn apart, are fed to said pin cylinder, substantially asdescribed.

2. Inainachine for the production of long staple fiber, a plurality ofrevoluble toothed feeding mills, a feed roller thereover, springsbearing upon said mills'to hold materials fed thereto in contacttherewith, a revoluble toothed cylinder having a line of teeth oppositeeach mill and a flexible bed comprising a plurality of plates, one lyingbetween each pair of mills, over which the material to be torn apart isfed to the toothed cylinder, substantially as described. In a machinefor the production'of long staple fiber, a plurality of toothed feedingmills, a shaft upon which said mills are assembled, means to rotate saidshaft, a feed roller to hold materials fed to the machine in closecontact with the mills, a revoluble pin cylinder having a row of teethin the plane of each mill, pivoted plates in the planes between themills, springs to give a certain flexibility to said plates and means todischarge the fiber produced away from the pin cylinder, substantiallyas described. In a machine for the production of long staple fiber fromcloth, revoluble feeding and holding mills, a plurality of feed rollsbearing upon said mills, a plurality of movable heads, springs connectedwith said heads and bearing upon the mills to hold the materials passingthereover in contact therewith, a pin cylinder revoluble closelyadjacent the mills and a flexible bed against which the materials fed tosaid machine are pulled apart by said pin cylinder, substantially asdescribed.

5. In a machine for the production of long staple fiber from cloth, afeed belt, a plurality of revoluble toothed feeding mills adjableadjacent said mills and said curvedplates, and means to discharge thematerials pulled apart by said pin cylinder from the machine,substantially as described.

In testimony whereof I have hereunto set my hand this 21 day of OctoberA. D. 1911, in the presence of the two subscribed witnesses.
